First I would like to welcome you to the Forum Darkshadow2468

I too had a reacurring nightmare when I was younger. Maybe younger than you. The dream consisited of a monster who would not allow me to save my mother. Anyway I one time in the dream connfronted the monster (dream character) and that was the last time I ever had that dream.
I too have overcome fears through Lucid dreaming because you have the abiluity to control the outcome.
So if your question is by being able to become lucid can help with insucurities and many other issues then yes, absolutly.
Is that what you are asking?
